Which of these is a starting point for primary succession?
A)
abandoned farmland
B)
a surface exposed by a retreating glacier
C)
a neglected yard
D)
an abandoned city

Correct Answer : Option (B) - a surface exposed by a retreating glacier



Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses.
